Abstract
The present invention relates to a run-in coating for a turbomachine, in particular for an aero engine, to be attached to a seal between a rotor and a stator, wherein the run-in coating comprises a metallic scaffold having interstices which are filled with an inorganic-nonmetallic filler material, and wherein the metallic scaffold is formed from an arrangement of metal fibers (9). The invention also relates to a corresponding turbomachine.
Claims3
A run-in coating for a turbomachine, wherein the run-in coating is for attaching to a seal between a rotor and a stator and comprises a metallic scaffold, which scaffold is formed from an arrangement of metal fibers and comprises interstices which are filled with an inorganic-nonmetallic filler material, wherein the metal fibers are formed from an FeCrAl alloy.
A run-in coating for a turbomachine, wherein the run-in coating is for attaching to a seal between a rotor and a stator and comprises a metallic scaffold, which scaffold is formed from an arrangement of metal fibers which are material-bonded to one another and comprises interstices which are filled with an inorganic-nonmetallic filler material, wherein the metal fibers are formed from an FeCrAl alloy.
A run-in coating for a turbomachine, wherein the run-in coating is for attaching to a seal between a rotor and a stator and comprises a metallic scaffold, which scaffold is formed from an arrangement of metal fibers which are sintered to one another and comprises interstices which are filled with an inorganic-nonmetallic filler material, wherein the metal fibers are formed from an FeCrAl alloy.
